Wired peer-to-peer confidentiality (WEP)
RC4 symmetric encryption technology is used at the link layer. The user's encryption key must be the same as the AP's key to allow access to network resources, thus preventing unauthorized user listening and unauthorized user access. WEP provides a 40-bit (sometimes called 64-bit) and 128-bit

WEP generally uses a 40bit/104bit (that is, some 10/26 hex keys on the wireless router) key k, and 24bit is a fixed v, so it can be said that it is a 64bit/128bit key, however, we
With the development of network technology, wireless network security has become more and more important. From what perspectives should we set up? Next we will introduce it to you.

First, develop a set of security policies
The first step to protect Web servers is to ensure that the Network Administrator understands every rule in the security policy. If the company's top management does not regard server security as an
Each layer of communication has its own unique security problems. Communication connections at the second protocol layer of the data link layer are relatively weak in terms of security. Network security issues should be addressed at multiple protocol layers for different vulnerabilities. In this article, we will focus

Regular changes to keys may also help protect the network. With any license, you should first choose to use WPA, because WEP may be decrypted by hackers using special software.

With the development of technology, the number of technical problems also increases. For wireless networks, improving or improving the security of networks also brings inevitable problems. Here we will introduce them in detail.

We recommend using password control on wireless network sites-of course, it is not necessary to be confined to wireless networks. Network operating systems and servers such as Novell NetWare and Microsoft NT provide built-in multi-level security services, including password management.
